ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

OBJECTIVE: To investigate the effectiveness of delayed replantation of degloving skin preserved at 4℃ in treatment of limb degloving injuries. METHODS: Between October 2020 and October 2023, 12 patients with limb degloving injuries were admitted. All patients had severe associated injuries or poor wound conditions that prevented primary replantation. There were 7 males and 5 females; age ranged from 29 to 46 years, with an average of 39.2 years. The causes of injury included machine entanglement in 6 cases, traffic accidents in 5 cases, and sharp instrument cuts in 1 case. Time from injury to hospital admission was 0.5-3.0 hours, with an average of 1.3 hours. Injury sites included upper limbs in 7 cases and lower limbs in 5 cases. The range of degloving skin was from 5 cm×4 cm to 15 cm×8 cm, and all degloving skins were intact. The degloving skin was preserved at 4℃. After the patient's vital signs became stable and the wound conditions improved, it was trimmed into medium-thickness skin grafts for replantation. The degloving skin was preserved for 3 to 7 days. At 4 weeks after replantation, the viability of the degloving skin grafts was assessed, including color, elasticity, and sensation of pain. The Vancouver Scar Scale (VSS) was used to assess the scars of the skin grafts during follow-up. RESULTS: At 4 weeks after replantation, 8 cases of skin grafts completely survived and the color was similar with normal skin, with a survival rate of 66.67%. The elasticity of skin grafts (R0 value) ranged from 0.09 to 0.85, with an average of 0.55; moderate pain was reported in 4 cases, mild pain in 3 cases, and no pain in 5 cases. All patients were followed up 12 months. Over time, the VSS scores of all 12 patients gradually decreased, with a range of 4-11 at 12 months (mean, 6.8). CONCLUSION For limb degloving injuries that cannot be replanted immediately and do not have the conditions for deep low-temperature freezing preservation, the method of preserving the degloving skin at 4℃ for delayed replantation can be chosen.

Objective To explore the feasibility and clinical outcome of lateral cervical incision via sternocleidomastoid intermuscular approach(SMIA)in the treatment of primary hyperparathyroidism.Methods The clinical data of 64 patients with primary hyperparathyroidism who underwent unilateral parathyroid surgery in the First Affiliated Hospital,School of Medicine of Zhejiang University from January 2019 to June 2022 were retrospectively analyzed.They were divided into lateral cervical incision via sternocleidomastoid intermuscular approach group(SMIA group)and linea alba cervicalis approach group(LACA group)based on the surgical incision and access route.The differences in clinical features,surgery-related outcomes and postoperative functions of the anterior cervical region were compared between the two groups.The EQ-5D-5L scale was used to assess the subjective feeling of postoperative neck discomfort,while the Hollander Wound Assessment Scale was used to assess the clinical outcome of incision healing.Results There were no statistical differences between the two groups of patients in terms of age,gender,intraoperative bleeding,parathyroid hormone or blood calcium levels before and after surgery(P＞0.05).The duration of surgery was significantly shorter in the SMIA group than in the LACA group[(39.77±5.69)min vs.(54.41±4.66)min].There was a statistical difference between the two groups in functional protection of the anterior cervical region at 1 month and 12 months after surgery(1 month,84.67±3.74 vs.79.47±5.38,P＜0.001;12 months,93.80±2.52 vs.89.94±2.39,P＜0.001),and the SMIA group was better than the LACA group.The Hollander Incision Assessment Scale scores of the SMIA group were better than those of the LACA group at 6 months and 12 months after surgery,and the difference was statistically significant(6 months,1.93±0.58 vs.2.41±0.66,P=0.003;12 months,1.03±0.67 vs.1.74±0.62,P＜0.001).Conclusion Parathyroidectomy via sternocleidomastoid intermuscular approach through lateral cervical incision is a simple,safe and effective surgical procedure,which makes it easier to search for parathyroid lesions and shortens the surgical time compared with the traditional incision,and has obvious advantages in the protection of anterior cervical region function.

Objective:To explore the current status of barriers to participation in phaseⅡcoronary artery bypass grafting (CABG) patients and the factors influencing them, and to provide new ideas for reducing barriers to participation in rehabilitation and improving the participation rate in cardiac rehabilitation.Methods:For this study, a cross-sectional survey research method was utilized. The study included 334 patients who underwent CABG and were admitted to the Second Hospital of Hebei Medical University between June 2022 and May 2023. These patients were selected using the convenience sampling method. A General Information Questionnaire, the Cardiac Rehabilitation Barriers Scale (CRBS-C/M), and a Questionnaire on the Knowledge of Information Related to Cardiac Rehabilitation were used to conduct the survey. Multiple linear regression was used to analyze the independent influencing factors on barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients.Results:Out of 334 patients, 248 were males and 86 were females with age (54.74 ± 7.61) years old. The total average score of CRBS-C/M in patients after CABG surgery was 3.20 ± 0.43, with the highest external logistic factors score of 3.42 ± 0.58. The knowledge status score of information related to cardiac rehabilitation was 42.11 ± 7.94. Multiple linear regression analysis revealed that the following factors independently influenced post-CABG patients′ barriers to participating in phaseⅡcardiac rehabilitation: marital status, whether or not they had completed phase I cardiac rehabilitation,number of other comorbidities, knowledge of cardiac rehabilitation information. All of these differences were statistically significant ( t values were -4.87-3.35, all P<0.05). Conclusions:The barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients are at an intermediate to high level, and healthcare professionals should emphasize the assessment of barrier factors in these patients, and target the development and implementation of phase Ⅱ cardiac rehabilitation in terms of the influencing factors.

Objective To identify the disease burden and indirect economic burden caused by lung cancer in Kunshan City, Jiangsu Province, from 1981 to 2020. Methods The incidence and death cases of lung cancer were obtained from cancer registry and death cause monitoring data. The disability adjusted life years (DALY) was used as the evaluation index for burden posed by lung cancer on health, and the indirect economic burden was calculated by a human capital method. Results From 1981 to 2020, a total of 9272 deaths due to lung cancer were reported in Kunshan, of which 7106 were males and 2166 were females. The DALY caused by lung cancer in the whole population were 3.81, 4.14, 4.38, and 9.46 in 1981–1990, 1991–2000, 2001–2010, and 2011–2020, respectively. The indirect economic burden caused by lung cancer was 10.515, 141.657, 813.794, and 6659.149 million yuan. From 2011 to 2020, the ratios of years of life lost due to premature mortality to DALY in males, females, and the general population were 92.42%, 95.15%, and 93.60%, respectively. Conclusion The health burden and indirect economic burden for lung cancer are substantial in the Kunshan City. Moreover, age-specific DALY and indirect economic burden are not exactly symmetrical, suggesting that an effective control strategy to lower cost is urgently needed, especially for individuals aged 40-59.

Based on the service of stranded patients in D Hospital, this study aimed to explore the multiple needs of stranded patients and construct an intervention mode from the ecosystem perspective. Using the method of case study, taking the service of stranded patients in hospital D as an example, 49 case records and verbatim interviews with stakeholders were analyzed. The discharge and resettlement of stranded patients faces multiple obstacles from individuals, families, medical and social systems. This study constructed the social work intervention model from the ecosystem perspective: information collection and needs assessment, empowerment of individual system, reconstruction of family support system, coordination of medical system and linking social support system. The intervention process achieved efficient effects. Social work intervention of stranded patients should pay attention to patients’ psychosocial needs and improve awareness of system difficulties; mobilize the multi-system support network and deliver services in combination with case management method; conduct social advocacy for the breakthrough of law and policy.

Objective:To explore the surgical techniques and effects of transfer of the free chimeric functional thoracodorsal artery perforator flap (TDAPF) with latissimus dorsi in reconstruction of dynamic muscle and soft tissue defects in forearm.Methods:From January 2014 to December 2020, a total of 13 transfer surgery of free chimeric functional TDAPF with vascularised latissimus dorsi were performed in the Department of Hand Surgery, Plastic & Reconstructive Surgery, Ningbo Sixth Hospital, to reconstruct forearm composite defects. The patients were 12 males and 1 female with an average age of 33.2 years old. They all had open forearm injuries, with 5 in the left and 8 in the right. Removal of inactivated muscles, exploration and repair of blood vessels and nerves were performed in emergency surgery, and VSD were applied after the surgery. Phase II reconstructive surgery were completed within 4 to 12 days, with 7.5 days in average. The wounds and flaps sized were 9.0 cm×8.0 cm - 21.0 cm×11.0 cm and were 10.0 cm×9.0 cm - 22.0 cm×12.0 cm, respectively. The volume of transferred muscles ranged were 9.0 cm × 2.0 cm × 1.5 cm - 19.0 cm × 9.0 cm × 1.5 cm. Free chimeric functional muscular flaps were transferred to reconstruct the musculus flexor digitorum profundus in 4 patients, the musculus extensor digitorum communis in 8 patients, the musculus flexor carpi radialis in 3 patients, and the musculus flexor pollicis longus in 1 patient. Reconstruction of both of musculus flexor carpi radialis and musculus extensor digitorum communis with 2 functional sub-blocks of latissimus dorsi were performed in 3 patients. All donor sites were closed primarily. All patients were included in the postoperative follow-up to evaluate the appearance of flaps, range of motion of the digits, recovery of muscle strength and gripping power, at the outpatient clinics or through the telephone interview.Results:A total of 12 flaps survived uneventfully after reconstructive surgery. One flap developed a vascular crisis and it was rectified after surgical exploration. Postoperative follow-up ranged from 17 to 52 months, with a mean of 34.1 months. Appearances of limbs and flaps were good without obvious bulky, hyperpigmentation or scar contracture. Four patients with reconstructed musculus flexor digitorum profundus showed muscle strength recovery of M 4, with the fingertips measured lower than 2.0 cm from the centre of palm when clenching a fist, and the average gripping strength of the hand reached 27.5% (20%-35%) to the healthy side. Five patients with reconstructed musculus extensor digitorum communis showed muscle strength recovery of M 4, and there was no obvious limitation in fingers flexion and extension, with the average gripping strength of the hand reached 75.4% (65%-80%) to the healthy side. Of the 3 patients with reconstruction of both power muscles, the recovery of muscle strength of musculus flexor carpi radialis was at M 4 in all the 3 patients, and the musculus extensor digitorum communis was at M 4 in 1 and M 3 in 2 patients. However, the patient who received reconstruction of musculus flexor pollicis had no significant recovery in muscle strength. Conclusion:Transfer of free chimeric functional TDAPF combines the benefits of a perforator flap and a functional muscle transfer together. This surgical technique can effectively reconstruct damaged muscle groups in forearm and resulting in good hand movement. Additionally, it can also restore the aesthetic appearance of forearm, hence makes it an excellent option for complex wound coverage.

Objective To investigate the predictive value of labor progress angle (AOP), fetal head descent distance (HPD) and their change rates in the outcome of vaginal trial of cesarean scar uterus. Methods A total of 170 pregnant women who underwent vaginal trial production of scar uterus after cesarean section were selected as study subjects, and were divided into successful group and failed group based on the trial production outcomes. Advanced oxidation processes (AOP) and head-perineum distance (HPD) were measured by ultrasound during the active phase of the first stage of labor when the cervix dilated to 4 cm and at 1 hour after the cervix dilated to 4 cm, respectively. The AOP change rate and HPD change rate after 1 hour of progress were calculated. The receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of AOP, HPD and their change rates in the outcome of vaginal trial production of scar uterus after cesarean section. Delong test was used to compare the differences in area under curves (AUCs). Results Among 170 pregnant women with scarred uterus after cesarean section who were pregnant again, 139 cases (success group) were succeed in transvaginal delivery, while 31 cases failed trial delivery, and transferred to cesarean section (failure group). The AOP of the successful group was significantly larger than that of the failed group when the cervix was opened to 4 cm, and the HPD was significantly shorter than that of the failure group (P < 0.05). The AOP change rate and the change rate of HPD of the successful group were significantly higher than that of the failed group when the cervix dilated to 4 cm and at 1 hour (P < 0.05). The AUC of AOP and HPD in predicting the outcome of vaginal trial delivery of scar uterus after cesarean section were 0.846 and 0.812 respectively, and AUC predicted jointly by AOP and HPD showed no significant differences compared with AUC predicted separately (P>0.05). The AUC of the change rate of AOP and HPD in predicting the outcome of vaginal trial delivery of scarred uterus after cesarean section was 0.899 and 0.852 respectively, and the combined prediction of AOP change rate and HPD change rate had a higher AUC value than the AUC predicted separately. Its AUC value was higher than that of AOP combined with HPD (P < 0.05). Conclusion The AOP, HPD and their change rates when the uterine orifice expands to 4 cm in the active phase of the first stage of labor have predictive value for the outcome of vaginal trial production of scarred uterus after cesarean section.

OBJECTIVE: To analyze the expression of hydroxysteroid dehydrogenase like 2 (HSDL2) in rectal cancer tissues and the effect of changes in HSDL2 expression level on proliferation of rectal cancer cells. METHODS: Clinical data and tissue samples of 90 patients with rectal cancer admitted to our hospital from January 2020 to June 2022 were collected from the prospective clinical database and biological specimen database. The expression level of HSDL2 in rectal cancer and adjacent tissues was detected by immunohistochemistry, and based on the median level of HSDL2 expression, the patients were divided into high expression group (n=45) and low expression group (n=45) for analysis the correlation between HSDL2 expression level and the clinicopathological parameters. GO and KEGG enrichment analyses were performed to explore the role of HSDL2 in rectal cancer progression. The effects of changes in HSDL2 expression levels on rectal cancer cell proliferation, cell cycle and protein expressions were investigated in SW480 cells with lentivirus-mediated HSDL2 silencing or HSDL2 overexpression using CCK-8 assay, flow cytometry and Western blotting. RESULTS: The expressions of HSDL2 and Ki67 were significantly higher in rectal cancer tissues than in the adjacent tissues (P < 0.05). Spearman correlation analysis showed that the expression of HSDL2 protein was positively correlated with Ki67, CEA and CA19-9 expressions (P < 0.01). The rectal cancer patients with high HSDL2 expressions had significantly higher likelihood of having CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T3-4 stage, and N2-3 stage than those with a low HSDL2 expression (P < 0.05). GO and KEGG analysis showed that HSDL2 was mainly enriched in DNA replication and cell cycle. In SW480 cells, HSDL2 overexpression significantly promoted cell proliferation, increased cell percentage in S phase, and enhanced the expression levels of CDK6 and cyclinD1 (P < 0.05), and HSDL2 silencing produced the opposite effects (P < 0.05). CONCLUSION The high expression of HSDL2 in rectal cancer participates in malignant progression of the tumor by promoting the proliferation and cell cycle progress of the cancer cells.

The retention of emergency patients is a common problem faced by hospitals worldwide. In addition to medical problems, social, family, economic and other problems will also cause patients to stay in the emergency department. It not only brings challenges to patients’ own disease treatment and hospital operation and management, but also brings ethical dilemmas. Taking the service cases of medical social workers who involved in stranded patients in Shanghai E Hospital as an example, this paper analyzed 20 service records and interviews with social workers receiving cases, and combed the ethical dilemmas faced by medical social workers in the process of involving in emergency stranded patients. It was found that medical social workers faced many ethical dilemmas in the process of involving in emergency stranded patients, such as interpersonal relations and relevant legal regulations, the right to life and health and the right to informed consent, the self-determination of case owners and the allocation of medical resources. In this regard, it is suggested to solve the problem of patient retention by advocating the improvement of relevant systems and policies, building cooperative teams to smooth referral channels, strengthening education, and promoting family shared decision-making.
